Brass won't neck size

[thirty06]

Have a new barrel in .223. Fired 100 times, went to neck size the 100 brass.
Backed off fl die 1/4 turn, sized body. Backed off die 1/2 turn it sized the body.
Turned the die 1 full turn from shellholder. it still sized the body.
This is a new, name brand barrel. Have neck sized much brass with these same dies
This only happens with brass from this barrel. Do I have an oversize chamber?

Read's like it. That's why I don't understand why some "neck size" with a FL die ??? Would it be a McGowen ?

[thirty06]

Didn't want to say, but yes it's a Mcgowen.

I neck size with neck sizing dies. I've never tried to neck size with a FL die. You can just add a neck die to your existing die set cheaply enough.

?

Just curious, could you put a caliper on the once fired brass and tell me how much they "growed" ?

[DGD6MM]

Measure your brass and if it is out of speck call McGowen, he stated on here that he will take care of his barrels.

Aint it lovely when someone start's a thread then leave's it :-\

1st- Don't normally neck size. Was trying anything to make this barrel shoot.
2nd-My sized brass measures .374 just above web .350 at body shoulder junction.

brass shot in Mcgowen .380 just above web .355 at body shoulder junction

Contacted Mogowen they said send barrel back + fired brass And my dies.
There not getting my dies' but I will send sized brass from dies.

I had 2 H&R Handi's that "grew" brass like that. Brass wouldn't last long shooting from that barrel. Thank's for the measurement.

Buy a neck die.

[thirty06]

Buying a neck sizing die won't fix the problem, it will just hide it.
I load for 4 different .223 and just like to be able to grab a box of
re sized brass and load. Like I said don't normally neck size' just trying
to make this barrel shoot decent. It doesn't shoot as good as the old
factory barrel I pulled off.

[trappst]

If your fired brass has stretched .006" just above the web area (start with new brass), that barrel needs to go back. You're gonna end up with a case head separation if you don't watch those cases like a hawk....

Be safe and have McGowen fix it.

[thirty06]

The barrel is going back to McGowen.
Just hope it's not within their specs.
Some thing is just not right with this barrel.

This is what is so frustrating for me. The McGowan barrel shoots worse groups than the factory barrel taken off the gun, which I have no idea how many rounds have been shot through it. I also bought a .223 blued, fluted from Northland for (by the way, Thirty06 is my father-in-law) my Father-in-law and this barrel will out shoot this "high dollar" barrel all day long.

By the way, Jim has contacted McGowan and gone to bat for us on this concern, and I just wanted to mention how much I appreciate Jim and all his hard work!!!!

Something is not right! I am looking at the SAMMI chamber specs for .223 Rem. and the maximum diameter .200 ahead of the head is .3789.

Sounds like some reamer chatter/wobble allowing it to cut oversize.

Just my $.02

Barrel is sent back. Now just wait and see what they say.
When I pulled the barrel I stuck a empty case in backwords
it went in over 1/4 in. Wouldn't go in the factory barrel at all.

I'm a dumb hillbilly, but that just don't make sense to me. How could a barrel like that get out the door ???

[thirty06]

Possum I'm with you.

Good new's is I guess they'll take care of you.
